Well, I can see you are not using an objective view. You own all Symbian devices. I own both and will continue to do so. There are some things that the BB OS does better, sorry, number one is stability. My BB has never rebooted or locked up, EVER. I cant say the same for my E51. The OS design of the BB is what makes its mail solution so sought after, no to mention how efficient and easy it is to use. There is no match on the market as far as security and remote management of the device, which is VERY important if you have to manage a few thousand of them. So to say that no one ever bought a BB because of the OS is just not true.
Dont get me wrong, I love both S60, and the BB, but because of its fantastic business handling capabilities, my BB is in my pocket 24/7/365. I play with my E51 when I need a quick shot with a cam or I need to make a VoIP call.
Every device and OS has its strength's and weaknesses depending on how we use the device. That difference forms our opinions. Neither is right or wrong.
Linux is in the public domain, so it truely IS open, but if there is a single entity CONTROLLING Symbian, then I hate to tell you, it is proprietary as well.
Proprietary does not mean its bad or good, it only specifies how control and changes can be made.
Symbian is a proprietary OS... taken right from wikopedia:
"Symbian OS is a proprietary operating system, designed for mobile devices, with associated libraries, user interface frameworks and reference implementations of common tools, produced by Symbian Ltd. It is a descendant of Psion's EPOC and runs exclusively on ARM processors.
Symbian is currently owned by Nokia (47.9%), Ericsson (15.6%), Sony Ericsson (13.1%), Panasonic (10.5%), Siemens AG (8.4%) and Samsung (4.5%). Although BenQ acquired the mobile phone subsidiary of Siemens AG, the Siemens AG stake in Symbian did not pass to BenQ."
